conauea'rnn WIRE-GLASS.

To all whom it may concern.

Be it known that we, WALTER Cox and Amvo SHUMAN, both citizens of the United States, and residents of Philadelphia, in the county of Philadelphiaand State of Penn'- sylvania, have jointly invented certain new and useful Improvements in Corrugated Wire- Glass, of which the following is a specification.

' The principal object of the present invention is to provide corrugated wire glass.

Inthe accompanying drawings there is illustrated, more or less, diagrammatically a machine and process and also the article,

and in those drawings- Figure" 1, is a longitudinal section of one type of machine. Fig. 2, a transverse section of the machine of Fig. 1, and Fig. 3, a

. perspective view of a piece of wire glass.

In Fig. 3, is illustrated the sheet of wire glass corrugated alike on both faces and of practically the same thickness at all points of the corrugations and having a wire mesh inclosed between. the surfaces of the sheet. Each surface presents a'continuous curve and repeatedly crosses the median plane of the sheet and the distance from center to center of the corrugationsis at least three times the'thickness of the glass.

Evidently the-sheet is possessed of great mechanical strength. The distance from center to center of the corrugations isconsiderable, and may be measured by saying that it is at least three times the thickness of-the glass, because. the glass is most advantageously employed in conjunction with corrugated sheet iron of which the corrugations are generally spaced at least three times as wide apart as the thickness of the ordinary sky-light glass. The fact that the surfaces of the corrugations crossfthe median plane of the sheet is a characteristic v p v signed our namesin the presence of of the article.

Specification of Letters I'atent.

.that is,

corrugated 1. A corrugated sheet of 'gations is at lea of the glass.

The table 1 transversely corrugated and i the rollers 2 and 3' are axially corrugated.

In operation each roller rolls a part of the the wire netting or mesh 4, is incorporated. 5 and 6 are lumpsor pours of glass, one 1n The mesh 4 may be introduced between the sheetand between the two parts of the sheet rolls, as shown or in front of the leading roller, all of which is well understood.

7, is a chute that may be employed for guiding the wire and the chute and rolls may be connected by a carriage 8. If desired the trangs 9 mav be removed so as to get the finished sheetofi the table sidewise, in the direction of the corrugations. The rolls and table by reason of their form, corrugate the sheet of glass and the wire mesh is also corrugated as it is incorporated into the glass. In the wire meshthe respective wires are twisted together as atlO, and

this line of twist operates as a kind of hinge or articulation about which the nettin may be comparatively easily bent. The llne of twist lies in the direction of the corrugations and in this way the-incorporation and corrugation of the netting as the sheet of glass is rolled, and corrugated is facilitated.

What we claimis:

glass in which each surface presents a continuous curve and repeatedly crosses the medianplane of the sheet and-having inclosed init a corrugated sheet of wire netting. I I

2. A sheet of wire glass corrugated alike on both faces and of practically the same thickness at all points of the corrugations and having a wire mesh inclosed between the surfaces of the sheet. and in which the distance from center to center of thefcorrust three times the thickness In testimony whereof wehave hereunto.
